[0052] Example 1

[0053] like Figures 1-23 As shown, the present invention discloses a wired control box assembly, including a housing 1 and a rear cover 2. The housing 1 and the rear cover 2 are detachably formed to form an installation space for accommodating a circuit board 4. The circuit board 4 includes a circuit board body 401, a temperature sensing element 403 is disposed on the circuit board body 401, and a separation notch 402 is disposed on the circuit board body 401. The temperature sensing element 403 is disposed on one side of the separation notch 402 and is disposed near the corner of the housing 1.

[0054] The temperature detection box assembly described in the present application detects temperature by setting a temperature sensing element (such as a temperature sensor, e.g. a thermistor or other sensor) on the circuit board 4, and by setting a separation gap 402 on the circuit board 4 to separate the temperature sensing element from other circuits or lines, thereby reducing the influence of heat conduction from other components on the circuit board on the temperature sensing element, improving the accuracy of the temperature sensing element, and thus more accurately detecting temperature without interference from heat generated inside the temperature detection box, while setting the circuit board 4 in the accommodation space between the detachably connected shell 1 and the rear cover plate 2, improving the convenience of installation and maintenance and the stability of connection of the circuit board 4.

[0055] The temperature detection box assembly described in the present application improves the accuracy of temperature detection by improving the environment of the temperature sensing element and reducing the influence of heat conduction, allowing users to more reliably control the air conditioner and improving the user experience.

[0056] As a preferred example of the present application, the temperature sensing element 403 is arranged at a corner position on the circuit board body 401, and the separation gap 402 is arranged in a bent shape. This arrangement sets the temperature sensing element 403 at a corner position on the circuit board body 401, which on the one hand allows it to be further away from elements on the circuit board that generate heat, thereby reducing the possibility of heat conduction to the temperature sensing element, and on the other hand facilitates the design of the separation gap 402 as an angularly varying or curved shape, which more effectively reduces heat conduction and improves the accuracy of the temperature sensing element, reducing distortion in temperature detection. As a preferred example of the present application, the length ratio of the connection portion of the circuit board body 401 at the position of the temperature sensing element 403 to the separation gap 402 is not greater than 0.3, and the length of the connection portion of the circuit board body 401 at the position of the temperature sensing element 403 refers to the vertical distance between the rear end point of the separation gap 402 close to the connection portion and the edge line of the circuit board body 401 close to the end point.

[0057] As a preferred example of the present application, a temperature sensing hole 101 is provided through the side end plate 103 of the shell 1 corresponding to the position of the temperature sensing element 403. This arrangement allows the temperature sensing element 403 to be installed in the relatively closed installation space formed by the shell 1 and the rear cover plate 2, and by providing the temperature sensing hole 101 in the side end plate 103 of the shell 1 close to the position of the temperature sensing element 403, which communicates with the outside space, it allows external air to flow through the temperature sensing hole 101 into the installation space to be accurately detected by the temperature sensing element 403, further improving the accuracy of temperature detection by the temperature sensing element 403 inside the temperature detection box assembly.

[0058] As a preferred example of the present application, the temperature sensing hole 101 comprises a first through hole 1011 and a second through hole 1012, which are respectively arranged on the two side plates of the side end plate 103 close to the temperature sensing element 403. As an example of the present application, the first through hole 1011 comprises a plurality of temperature sensing through holes arranged in an intermittent manner, and the second through hole 1012 comprises a plurality of temperature sensing through holes arranged in a continuous manner. This arrangement further improves the reliability of the external air entering the inside of the wire control box assembly being accurately detected by the temperature sensing element 403, ensuring that the air conditioning system works more effectively and provides a more comfortable environment.

[0059] As a preferred example of the present application, an intermediate pressing plate 3 is arranged between the circuit board 4 and the rear cover plate 2, and the intermediate pressing plate 3 is fixed with the shell 1 by connecting screws. An avoidance corner 301 is arranged on the intermediate pressing plate 3 corresponding to the position of the temperature sensing element 403.

[0060] This arrangement, by arranging the intermediate pressing plate 3 with the avoidance corner 301, on the one hand ensures the support and fixation of the shell 1 and the internal circuit board body 401 and other electrical elements of the rear cover plate 2, and on the other hand ensures that the intermediate pressing plate 3 does not conflict with the temperature sensing element 403 on the circuit board 4, thereby achieving effective assembly and temperature monitoring of the device.

[0061] As a preferred example of the present application, a wiring terminal 6 is arranged on the circuit board body 401, which is inserted into the circuit board body 401 by a pin and then welded and fixed. The wiring terminal 6 is fixed by a wire screw. As a preferred example, the wiring terminal 6 comprises a wiring board 603, a limiting plate 601 is arranged on the opposite ends of the wiring board 603, the limiting plate 601 is arranged on the side of the wiring board 603 away from the circuit board body 401, and a plug-in plate 602 is arranged on the other opposite ends of the wiring board 603, the plug-in plate 602 is arranged on the side of the wiring board 603 close to the circuit board body 401, the wiring board 603 is connected to the circuit board body 401 by the plug-in plate 602, and a screw gasket 604 is arranged on the wiring board 603. In this arrangement, the limiting plate 601 can limit the screw gasket 604 of the wire electrical connection, reducing the risk of improper wiring operation. At the same time, the limiting plate 601 can separate adjacent wiring terminals 6, further avoiding short circuit phenomenon caused by contact between adjacent wiring terminals 6.

[0062] As a preferred example of the present application, a plug-in terminal 8 is provided on the circuit board body 401, which is connected to a plug-in wire. The connection mode of the plug-in terminal 8 is different from the connection terminal 6 fixed by wire screwing as described above, and the connection is fixed by plug-in mode, making it easier and faster to plug in and pull out, especially suitable for situations that require frequent replacement or disassembly, improving the efficiency of maintenance and repair.

[0063] As a preferred example of the present application, an avoidance slot 9 is provided on the intermediate pressing plate 3 corresponding to the positions of the connection terminal 6 and the plug-in terminal 8.

[0064] As a preferred example of the present application, a USB connection hole 102 is provided on the side end plate 103, and a rubber plug 5 is provided at the USB connection hole 102, which can close or open the USB connection hole 102.

[0065] This setting allows the circuit board 4 in the wire control box assembly to interact with external devices or charge other USB devices through the USB connection hole 102, and the design of the rubber plug 5 allows the USB connection hole 102 to be selectively opened or closed. When the plug is closed, the USB connection hole is isolated, preventing dust, moisture or other external substances from entering the wire control box assembly, protecting the internal circuit from the external environment; when the plug is open, the user can easily connect the USB device. This setting increases user friendliness, helps provide a better user experience, and provides the possibility for future functional expansion for configuration, upgrade or data transmission, increasing the multifunctionality and customizability of the wire control box, facilitating the update iteration of the circuit board 4 control program.

[0066] As a preferred example of the present application, the rubber plug 5 includes a connecting body 501, a sealing boss 502 is provided on one side of the connecting body 501, and the sealing boss 502 can be in sealing contact with the plug-in port 1021 on the USB connection hole 102.

[0067] This setting discloses a specific structure of the rubber plug 5, ensuring the sealing contact of the rubber plug 5 with the plug-in port of the USB connection hole 102, improving the protection, waterproofness and dustproofness of the wire control box assembly, protecting the internal components, reducing maintenance costs, and providing a better user experience.

[0068] As a preferred example of the present application, a rotating buckle 503 is arranged on the connecting body 501, which is arranged on the same side of the connecting body 501 as the sealing boss 502, and can rotate relative to the rotating shaft hole 1022 on the USB connecting hole 102. As an example of the present application, the rotating buckle 503 includes a rotating shaft part 5031 and a limiting part 5032, the limiting part 5032 is arranged at the end of the rotating shaft part 5031 away from the connecting body 501, the rotating shaft part 5031 passes through the rotating shaft hole 1022 and is axially limited by the limiting part 5032.

By arranging the rotating buckle 503, the position and direction of the rubber plug 5 are adjusted, the convenience and applicability of use are improved, the operation is simple, the rotating operation is stable and controllable, and at the same time, the rubber plug 5 is also prevented from completely separating in the state of opening the USB connecting hole 102, preventing the rubber plug 5 from being lost.

[0069] As a preferred example of the present application, a handle 504 is arranged on the side of the connecting body 501 away from the sealing boss 502.

[0070] This arrangement further improves the convenience of user operation.

[0071] As a preferred example of the present application, a panel 7 is arranged on the side of the shell 1 away from the rear cover plate 2, and the panel 7 is detachably connected with the shell 1. This arrangement protects the operation keys of the drive-by-wire box assembly from being touched by foreign objects and causing misoperation, and also improves the integrity and aesthetics of the drive-by-wire box assembly.

[0072] The drive-by-wire box assembly described in the present application improves the accuracy of temperature detection of the temperature sensing element 403 in the drive-by-wire box assembly by arranging a notch (separation notch 402) on the circuit board 4 and arranging a temperature sensing element 403 at the notch to block the transmission of heat from the circuit board to the temperature sensing element.
